What role can sulfur play in the makeup of amino acids and proteins?

Sulfur is part of the structure of some amino acids and proteins.

Explanation:

Sulfur enters the disulfide layers in proteins and is responsible for their spatial structure. Many proteins, in order to perform their function, need a stable spatial form (Enzymes, for example.). Because disulfide bridges form strong bonds between amino acids, this structure remains strong and stable to perform its function.  In addition, sulfur is present in the amino acids cystine, cysteine and methionine contained in proteins. Proteins are the compounds in which most of S and N are incorporated. Sulfur content in proteins is 1 g / kg and N is 15 times higher.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
