reactions (catalysts)‚ hormones that regulate bodily activities‚ structural proteins that provide support‚ such as with keratin and collagen‚ found in connective tissues‚ storage proteins store amino acids‚ transport proteins carry molecules/nutrients from one place to another (i.e. hemoglobin). Also contributes to acid base balance as buffers. Forms glucose through gluconeogenesis. Muscle wasting is cachexia. Protein also provides 4kcal/g Protein sources in the diet: Either diet or recycling of body protein

Chapter 2 Chapter 2 is about Molecular level of life/ the chemical component of life. What does chemistry have to do with our life? Chemical aspect of life. Matter: anything in the universe that has weight and occupies space. The weight is called mass. The mass will remain constant regardless of gravity. Can exist in our body in three different forms Three states of matter in our body. * Solid: in our body are organs‚ Bones‚ they will have different shapes. * Liquid: In our body
Premium Protein Hydrogen Atom
Proteins are made up of long chains of amino acids‚ just a chain of ami. tacids makes up the primary structure. The secondary structure is formed by hydrogen bonds joining the chains in certain places to make an alpha helix or a beta sheet. The tertiary structure is formed by even more folding and joining of the chains to make a globular mass or fibrous mass. An example of this would be a carrier protein. Proteins are needed for many things they are needed in our diet for growth and repair of cells
Premium Protein Amino acid
are part of each organ‚ tissue‚ and cell within the human body. The protein in consumed food turns into amino acid. The amino acid is used later replinish the proteins used. Proteins have two structures. the first and primary structure of protein is the sequence of the amino acid in the protein (Kim‚ 2005). The amino acid is clutched together by peptide bonding‚ meaning that the amino acid clutches to carboxyl groups by using a dehydration type of synthesis. This classification is decided by

Objectives After studying this Unit‚ you will be able to • define the biomolecules like carbohydrates‚ proteins and nucleic acids; • classify carbohydrates‚ proteins‚ nucleic acids and vitamins on the basis of their structures; • explain the difference between DNA and RNA; • appreciate the role of biomolecules in biosystem. Biomolecules “It is the harmonious and synchronous progress of chemical reactions in body which leads to life”. 14 Unit A living system grows‚ sustains and reproduces

The essential amino acid phenylalanine‚ with the molecular formula C9H11NO2‚ is abbreviated in the 3 letter form as Phe‚ or the single letter F‚ and is classified as a nonpolar amino acid due to the hydrophobic nature of the benzyl side chain (UPAC-IUBMB Joint Commission on Biochemical Nomenclature‚ 1983). The presence of the benzene ring determines that phenylalanine is an aromatic amino acid. Phenylalanine‚ being an essential amino acid‚ is needed by the body for many necessary biological functions

Chained Amino Acids for Muscle Building and Recovery 1. Introduction A. Consumed for pre-workout‚ during or post workout. B. Where they are found: Different types of animal proteins we consume and different supplements on the market 2. What are BCAAs A. Examples: L-Leucine‚ Citrulline Malate‚ Beta Alanine‚ L-Isoleucine‚ L-Valine‚ and alpha-Hydroxyisocaproic Acid (HCAA) B. They are the building blocks of proteins‚ form coenzymes (coenzymes are essential for enzyme
Premium Amino acid Protein
four different chemical groups: monosaccharides‚ disaccharides‚ oligosaccharides‚ and polysaccharides. Monosaccahrides are the simplest form of the carbohydrate. Monosaccharides are important fuel molecules as well as building blocks for nucleic acids. A monosaccharide is similar to a DNA
Premium Protein Nutrition Amino acid
chains of amino acids that perform the most important functions in living organism. Every protein will contain an amino group‚ carboxyl group‚ a different R group and an alpha carbon with two hydrogens. There are nine types of functions proteins can have‚ enzymes‚ motor‚ receptor‚ structural‚ storage‚ transport‚ signaling‚ and special purpose proteins(antibodies). There are four levels of protein structure‚ primary‚ secondary‚ tertiary and quaternary. Level one( Primary) deals with amino acid sequencing
