Explanation
-Scurvy is a disease caused by a deficiency of vitamin C or ascorbic acid in the body. Vitamin C plays an important role in the production of collagen, which is a protein that helps to form connective tissues in the body. When there is a lack of vitamin C, the body is unable to produce enough collagen, which leads to the symptoms of scurvy. -Retinol is a form of Vitamin A.Vitamin A deficiency can result from inadequate intake, fat malabsorption, or liver disorders. Deficiency impairs immunity and hematopoiesis and causes rashes and typical ocular effects (eg: xerophthalmia, night blindness). -Tocopherol or vitamin E mproves sperm motility (movement).Vitamin C functions to regenerate vitamin E; thus, these vitamins may work together to improve sperm function. Vitamin C increases sperm count, motility, and morphology. -Thiamin(thiamine), or vitamin B1,is a water-soluble vitamin.Compared to baseline, thiamin-supplemented women experienced significantly increased appetite, energy intake, body weight and general well-being, and decreased fatigue.So low thymine levels results in loss of apetite.

About Macromolecules
Proteins are classified by shape, composition and structure, from primary amino acid sequence to secondary, tertiary and quaternary organisation, and their biological roles are linked to this structure. Enzymes are examined as protein biocatalysts, including active sites, substrate specificity, activation energy, cofactors and factors affecting activity.
