In the skeletal system, which are the two main tissues responsible for structural support in the body?

The answer is the compact bone and ligaments. The skeletal system supports and protects the body while giving it shape and form. It is composed of connective tissues including bone, cartilage, tendons, and ligaments. Nutrients are provided to the skeletal system through blood vessels that are contained within canals in bone. Tendons, bones, joints, ligaments and muscles work in concert to produce various movements

kym t

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
