Fat- and Water-soluble Vitamins Vitamins are primarily classified by solubility. Some vitamins are soluble in water and others are soluble in fat. “According to The National Institute of Health‚ the body needs 13 vitamins for normal health.” This includes vitamins A‚ C‚ D‚ E‚ K and the B complex vitamins‚ thiamine‚ riboflavin‚ niacin‚ pantothenic acid‚ biotin‚ B6‚ B12 and folate. Each of these vitamins provides a variety of functions to the body which can be obtained from a well balanced diet

EXPERIMENT NO. 12 DIGESTION IN THE STOMACH ABSTRACT____________________________________________________________________________ Digestion refers to the mechanical and chemical breakdown of food into smaller components that can undergo absorption. The objective of this experiment is to investigate mainly the process of digestion in the stomach. The conditions at which the enzymes responsible for the digestion process were determined. Also‚ the total and free acidity of gastric juice of the sample

Digestion and Nutrients Briana Smallwood The human body needs nutrients for it to survive. Nutrients are the fuel for the body to do work. It helps the body grow‚ provide protection from sickness and disease‚ function properly‚ and even live. There are many types and forms of nutrients that each do specific or multiple jobs. They are classified in six main groups. Carbohydrates‚ proteins‚ fats‚ vitamins‚ minerals and water are all the different groups. Proteins are nutrients that help build and

Energy in context Introduction Digestion is the breakdown of large insoluble food molecules into smaller molecules so they can pass though the intestinal wall into the bloodstream and be transported throughout the body. There are seven different food groups in a balanced diet which should include Carbohydrate‚ fat‚ water‚ protein‚ fibre‚ vitamins and minerals. Although most foods contain these in some shape or form the foods that contain most of one type fall into that category‚ a chicken

Digestion a. The mouth: salivary alpha enzyme chew food‚ perceive taste‚ moisten food with saliva‚ lubricate food with mucus‚ release starch –digesting (amylase) enzymes‚ initiate swallowing reflex - Enzyme: alpha amylase with cooked starch as substrate – starch digestion enzyme an enzyme that catalyses the breakdown of starch into sugar - The Functions of Saliva - 1. Moistens and lubricates food‚ permitting swallowing 2. Holds taste producing substances in solution and bring them in
