Proteins Are the basic materials of every body cell. Body cells are constantly wearing out. As a result, they are continuously in need of replacement Of the six nutrients group, only proteins can make new cells rebuild tissue. By the age of 4 years, body protein content reaches the adult level of about 18% of body weight. An adequate supply of proteins in the daily diet is essential for the maintenance of health. The word protein is a Greek derivation and means “of first importance”. Composition...

Effect of Protein Intake on Strength, Body Composition and Endocrine Changes in Strength/Power Athletes Introduction: Proteins are often called the building blocks of the body. Protein consists of combinations of structures called amino acids that combine in various ways to make muscles, bone, tendons, skin, hair, and other tissues. They serve other functions as well including nutrient transportation and enzyme production. Adequate, regular protein intake is essential because it isn’t easily...

PROTEIN TRANSLATION 1. Initiation Translation To begin translation: large and small ribosomal subunit, along with the initiating tRNA, assembles onto the mRNA 2. Translation Elongation The next amino acyl-tRNA enters the ribosome at the A site The amino acid at the P site is transferred to the tRNA at the A site. The ribosome moves one codon farther along the mRNA, releasing the empty tRNA through the E (exit) site. The A site is free for the next incoming RNA. The cycle is repeated as the...

Protein Synthesis

Identifying sites of protein synthesis in Chlamydomonas using erythromycin and cyclohexamide as protein synthesis inhibitors. October 16, 2009 Introduction: In living cells, prokaryotic or eukaryotic, the synthesis (construction) of proteins is accomplished by similar machinery. Amino acids, ribosomes, messenger RNA (mRNA), and transfer RNA (tRNA), are all necessary for the building of functional proteins in a cell. Ribosomes are the site of protein synthesis in a cell, and there are two...

Protein Metabolism

Proteins play an important role in the human body. The DNA molecule controls the synthesis of proteins. The DNA contains genes which are sequences of nucleotides and bases. Proteins are used for growth and repair. Proteins are made up of amino acids linked together by peptide bonds. Firstly 'amino acid synthesis' is the set of biochemical processes by which the various amino acids are produced from other compounds. The substrates for these processes are various compounds in the organism's diet...

Protein and Beetroot

used were 2,4,7,9 and 10. All of these solutions affected the beetroot, but the most acidic solutions were the ones that did the most damage to the membrane. This is because the ph affects the proteins within the phospho lipid bi-layer. The acidic ph breaks the hydrogen bonds therefore denaturing the proteins and allowing beetroot pigment to secrete form the cell. 7. The ethanol solutions that were used were 11%, 25% and 50% ethanol. The beetroot cell was almost immediately affected by the 50% alcohol...
