Salty Origins for Early Earth Biomolecules

All of the sentences in English are from the website:

The early Earth's oceans were home to a lot of interesting chemistry.
不知道怎麼翻
google譯：
早期地球的海洋是回家了很多有趣的化學。
冏～太天兵了
改正：早時地球的海洋是家，孕育許多有趣的化學變化
應該是這樣吧！高手請指證

amino acids氨基酸

Scientists have found that amino acids thought to be present way back when could have been cooked into other
compounds vital for life-an idea you should take with a grain of salt.
神奇的文法,看不懂中


Four billion year ago, the planet was probably covered
by a salty ocean, dotted with volcanic islands and short lived continents.

mimic 模仿

German researchers recently mimicked some of the chemistry taking place
along the coasts of the volcanic islands.

primordial最原始的

They created an approximation of primordial seavater.

simulate 模仿
residue 殘渣
crusts 地殼

they evaporated it, to simulate what went on at those volcanic coasts.
they baked the residue, creating salt crusts.

pyrroles
chlorophyll 葉綠素
hemoglobin 血紅素

At those high temperatures, amino acides interacted with metal
ions in the salt crusts and were converted into other important
biological molecules, such as pyrroles-which are part of the
structures of chlorophyll in plants and hemoglobin in animals.

Over hundreds of thousands of years, these novel compounds could
have built up along the volcanic coasts, creating materials for
the first living cells. Which were really worth their salt.
最後一句是？ which 是指 compounds ，compounds是真的有價值的他們的鹽 XDD這是我翻的
